Teaching Statistics in US — An Alien's s-eye View     

Oliver D. Anderson 《Teaching Statistics》1989,11(1):12-15

This article discusses the author's initial experience of teaching statistics in an American university, and the sort of way he thinks the subject should be taught. (Specifically, he looks at the assumption of normality, and indicates how conventional treatment in the area of hypothesis testing might be modified.) His comments primarily apply to elementary service courses, and particularly to those provided for business students.  相似文献   

王国维、蔡元培美育思想之比较——兼论王国维、蔡元培的人文教育精神     

刘虹  张秀坤 《教师教育研究》2003,15(6):68-72

在中国近代美育史上,王国维和蔡元培是两位最具影响力的人物。王国维在近代中国首倡美育,是近代中国美育理论的创始人。蔡元培率先实行美育,毕生提倡、亲身实践美育,普及美育理论,最终确立起美育的重要地位。王国维和蔡元培的美学观都以康德哲学为基础,同时他们的美育思想都闪耀着人文主义的光芒。但二者对美育的阐释又有很大的区别,对美育建立的具体作用也不尽相同。本文从比较研究的角度出发,从几个方面,尤其从文化人格和人文教育精神方面揭示二者在美育的建构中表现出的共同性和差异性。  相似文献   

Three studies of factors affecting the attitudes of blacks and females toward the pursuit of science and science-related careers     

Oliver W. Hill  W. Clinton Pettus  Barbara A. Hedin 《科学教学研究杂志》1990,27(4):289-314

This study involved the development of an instrument, the Science Career Predictor Scale (SCPS), which assesses seven factors thought to be involved with science career choices: teacher/counselor encouragement, participation in science-related hobbies and activities, academic self-image, science-related career interest, parental encouragement and support, the perceived relevance of mathematics and science, and mathematics and science ability. This instrument was administered to a sample of 522 middle and high school students, and a sample of 185 students from an historically black university, and the effects of such factors as sex, race, personal acquaintance with a scientist, and type of community (rural or urban) on the above-mentioned variables were ascertained using a multivariate analysis of covariance with age as the covariate. A separate study on a sample of 81 high school students looked at race and gender differences in critical thinking abilities as measured by the Watson-Glaser Critical Thinking appraisal, and how these abilities correlated with scores on the Science Career Predictor Scale. These studies produced several significant findings. Female subjects did produce significantly lower scores on the career interest factor. Black students actually had significantly higher science-career preference scores than their white counterparts. However, blacks scored significantly lower on the measure of critical thinking ability. Across both races and both sexes, however, the major factor affecting science-related career decisions appears to be personal contact with a scientist. The implications of these findings are discussed, along with possible strategies for increasing the participation of these groups in science.  相似文献   

Optical computing   总被引：3，自引：0，他引：3  

Debabrata?GoswamiEmail author 《Resonance》2003,8(7):8-21

Researchers are using new conducting polymers to make transistor-like switches that are smaller and thousand times faster than the silicon transistors. Electricity-conducting organic molecules that are much thinner than semiconductor wires, are being teased into self-assembling. These advances promise super-tiny all-optical chips. In fact, progress in optical storage devices can now shrink an entire Library’s book collection down to sugar-cube size. Optical computers could be leaving silicon number crunchers choking in the dust by decade’s end.  相似文献   

Why Universities Need Institutional Researchers and Institutional Researchers Need Faculty Members More Than Both Realize     

Ronald?G.?EhrenbergEmail author 《Research in higher education》2005,46(3):349-363

This paper provides an overview of research that I have conducted during my career using data sets collected by offices of institutional research. Many of the examples discussed in the paper deal with graduate education. The paper illustrates how valuable the data collection efforts by these offices are to academic researchers interested in helping to formulate institutional, state and national higher education policies. It concludes with suggestions for how the usefulness of institutional researchers to colleges and universities can be improved and stresses that institutional researchers and administrators would be wise to involve more faculty members in research that aids in institutional decision making and the formulation of public policy towards higher education.  相似文献

The effects of formal learning and informal learning on job performance: the mediating role of the value of learning at work     

Yoonhee?Park  Woojae?ChoiEmail author 《Asia Pacific Education Review》2016,17(2):279-287

Although research has widely recognized the relationships between formal and informal learning and job performance, empirical studies have not paid sufficient attention to these relationships. In addition, there is little understanding how individual perceptions toward learning influence the relationships between the aforementioned two types of learning and job performance. In the present study, it was proposed that formal and informal learning can influence job performance. Moreover, in the relationships between formal and informal learning and job performance, the value of learning at work was considered as a mediator. With a sample of employees from small and medium-sized enterprises in South Korea, the research showed that formal and informal learning influences job performance through the value of learning at work. Based on the results of the study, several implications were discussed.  相似文献   

Anxiolytic-like effect of ejaculation upon frustration     

Freidin E  Kamenetzky G  Mustaca AE 《Learning & behavior》2005,33(3):277-286

In three experiments, we studied the consequences of ejaculation upon the frustrative or contrast response of male rats exposed to reward downshift situations (i.e., surprising changes from 32% to 4% sucrose solutions). Similar to what has been found after treatment with anxiolytic agents, consummatory suppression was partially reversed by previous ejaculations in a second postshift trial (Experiments 2 and 3), such a result not having been obtained in a first postshift trial (Experiment 1). Moreover, the effect of ejaculations upon males' behavior during a second postshift trial was transitory, disappearing when assessed during the third and fourth postshift trials (Experiment 3). These results are in accordance with both Amsel's (1958, 1992) frustration theory and Flaherty's (1996) multistage hypothesis of successive negative contrast; the diverse factors that are known to modulate contrast effects are considered, including an interpretation of the present data in terms of the anxiolytic-like effect of the ejaculation.  相似文献   

Safe Schools/Healthy Students initiative: Pinellas County,Florida     

Kathleen Hague Armstrong  Oliver T. Massey  Michael Boroughs  Ralph Bailey  Diane LaJoie 《Psychology in the schools》2003,40(5):489-501

The Safe Schools/Healthy Students (SS/HS) Initiative in Pinellas County, FL, emerged as a part of a broader local effort to implement creative educational and mental health programs to support children and families. This initiative focused on capacity building, prevention, and intervention efforts and comprehensive evaluation to address the barriers to learning and enhance healthy development. This article describes Pinellas County's plan, and highlights the instrumental roles played by school psychologists, which included grant writing, program and resource coordination, clinical services, program evaluation, staff training, parent advocacy, and steering committee membership. Promising outcomes and generalization of these findings to other communities is also discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 489–501, 2003.  相似文献
